Purchased at a British antique shop for 300,000 yen. Early 19th century, a custom-made shot glass with three dice inside, likely used for games while drinking. The cutting features MANS, R u iN, cards, a wine glass, and a face, all custom-ordered. The bottom has a 3cm space containing three dice in a sealed state, showcasing superb craftsmanship. The material of the dice is unknown. Due to its antique nature, there is some cloudiness inside the dice space. Diameter: 5.4cm Height: 8cm Dice space: 3cm. I will respond to questions and provide additional photos. As this is a sale with the understanding of the buyer, returns are not accepted. It will be wrapped in cushioning material and packed in a cardboard box for shipping. Thank you.
